This is a south African set. We are in North America, so this link should work better for you.

You can try a power reset, remove the mains plug overnight.

Or you buy a new remote. ALL televisions need a remote. You need the model number.

The backlight led is burnt out, time to replace with new one. Most of the time it’s only 1-2 led are burnt. You need an electronic technician though. I may guide you if you want further assistance.

If you have restored the TV to its manufacture factory setting and still have the same issues, and also have tried to adjust it manually, more likely your TV is going out soon and needs to repair by the certified electronic repair facility. Because of the brand/model, is really not worth fixing. By the time you invest fixing it, you can by a brand new TV from Walmart a Sharp, JVC and Toshiba 55' for under $300 bucks. In addition, there's no setting you can do or adjust to resolve your TV issues when it comes to LED colors malfunction. If this is a Dixon 55" TV, it an OK brands. Dixon, Sinotec, and Hisense are cheap TV, and I doubt you going to get a good service longevity out of those bands.

The set has an internal fault and needs to be serviced
